Meyer Sound UP-4XP UltraCompact Loudspeaker

Product Description

The Meyer Sound UP-4XP UltraCompact Loudspeaker is designed for applications requiring a small, inconspicuous cabinet that also delivers high sound pressure levels, low distortion, and uniform directional control. The self‑powered UP‑4XP offers exceptional audio performance in a compact package with the advantages of a remote power supply. As a standalone loudspeaker, the UP-4XP is ideal for vocal reinforcement, front fill coverage, and delay coverage for under‑balcony applications. Alternatively, pairing the UP‑4XP with an optional subwoofer creates a full-range system.

The unit’s high‑frequency section includes a 1-inch metal dome tweeter on a constant‑directivity, high-frequency horn with a 100° beamwidth. The low/mid-frequency section includes two 4-inch cone transducers that work in parallel at low frequencies—delivering a combined acoustic output—with one of the drivers rolling off at higher frequencies to prevent interference (due to comb filtering effects) in the crossover region. Three channels of on-board power amplification, which include an active crossover, driver protection, and frequency and phase correction circuitry, power the proprietary UP‑4XP drivers that Meyer Sound manufactures in its Berkeley, California factory. With IntelligentDC technology, the UP‑4XP receives DC power and balanced audio from a single loudspeaker connector. Powering the unit from an external source eliminates the need for wiring conduits while still preserving the advantages of self‑powered systems. The UP‑4XP’s amplifier and signal‑processing circuits store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and lengthy cable runs.

The UP‑4XP requires an external Meyer Sound IntelligentDC power supply. The MPS‑488HP single-space rack-mount unit distributes DC power and balanced audio to up to eight UP‑4XP loudspeakers or other Meyer Sound IntelligentDC loudspeakers. For smaller installations, the 1RU one-half width rack-mount MPS-482HP IntelligentDC power supply offers two channels of audio and DC power. Composite multiconductor cables, such as Belden 1502 or equivalent, can deliver both DC power and balanced audio to loudspeakers at cable lengths up to 150 feet with just 1 dB of loss in peak SPL using 18 AWG wire. Longer cable lengths are possible with heavier gauge wires. Meyer Sound’s RMS remote monitoring system module, which provides comprehensive monitoring of loudspeaker parameters from a host computer running Compass software, is optionally available for the MPS-488HP.

Meyer Sound coats the UP‑4XP’s durable cabinet with a slightly textured black finish and includes top and bottom mounting plates with 3/8-inch-16 or metric M10 threaded nuts.
